Abstract
r”0 experiments were performed at the Research Farm of Animal
Department, Faculty of Agriculture, AL-Azhar university- Assiut
study aimed to evaluate and compare between the impact of three models (traditional, non-traditional and underground models), varied
r1sulative efficiency on the productive and reproductive performance of irabbits under the prevailing climatic conditions in Assiut. It lasted about
s from June till December, 2009, including two successive seasons; the iiner (June, July, August and September)v followed by the mild autumn r, November and December), respectively.
The experimental models differed in their design, constructing materials Ønsequently in their isolative potentiality. In the first model (traditional),
‘ills are made of concrete bricks with 12.5cm thickness and the roof
of a corrugated galvanized steel sheets covered with a second corrugated os sheet layer. In the second model (non-traditional), the walls of 5 0.0cm .jess are made of mud bricks (adobe), coated with 3.0cm layer of fermented ,‘with cut-wheat straw, while the roof consisted of palm branches with leaves
d mud layers, respectively.
In the third model (underground), the walls are built of stone bricks
40.0cm thickness and the roof is made of 20cm concrete layer except one
meter used as a window. The outer surface of the concrete roof was
cred with 30.0cm mud.
In the present study, forty two Bouscat rabbits (24 does and 18 bucks), 7 iths old were divided into three equal groups. In the first, rabbits were housed 1ie traditional model and considered as the control, while in the second and id groups, were kept in the non-traditional and underground models,
